通過Android系統提供的介面，可以很方便的管理聯絡人資訊。

一、新增

1、新增聯絡人
1.6上的程式碼：

String peopleName = "name";ContentValues personValues = new ContentValues();// namepersonValues.put(Contacts.People.NAME, peopleName);/* STARRED 0 = Contacts, 1 = Favorites */personValues.put(Contacts.People.STARRED, 0);Uri newPersonUri = Contacts.People.createPersonInMyContactsGroup(getContentResolver(), personValues);

2.1時需要用下面的程式碼才可以新增：

String peopleName = "name";ContentValues personValues = new ContentValues();// namepersonValues.put(Contacts.People.NAME, peopleName);newPersonUri = getContentResolver().insert(People.CONTENT_URI, personValues);

2、新增電話號碼
根據TYPE的不同，可以新增不同型別的電話號碼。

1.6上支援的TYPE有：TYPE_CUSTOM，TYPE_FAX_HOME，TYPE_FAX_WORK，TYPE_HOME，TYPE_MOBILE，TYPE_OTHER，TYPE_PAGER，

TYPE_WO

Uri uri = null;ContentValues values = new ContentValues();// add phone numberString tel = "86-21-65432100";if (!AppUtils.isEmpty(tel)) {values.clear();uri = Uri.withAppendedPath(newPersonUri, Contacts.People.Phones.CONTENT_DIRECTORY);values.put(Contacts.Phones.TYPE, Contacts.Phones.TYPE_HOME);values.put(Contacts.Phones.NUMBER, tel);getContentResolver().insert(uri, values);}

3、新增Email地址
通過改變KIND的值，可以新增不同的聯絡方式。
1.6支援KIND_EMAIL，KIND_IM，KIND_ORGANIZATION，KIND_PHONE，KIND_POSTAL

// add email addressString email = "abc@com.cn";if (!AppUtils.isEmpty(email)) {values.clear();uri = Uri.withAppendedPath(newPersonUri, Contacts.People.ContactMethods.CONTENT_DIRECTORY);values.put(Contacts.ContactMethods.KIND, Contacts.KIND_EMAIL);values.put(Contacts.ContactMethods.DATA, email);values.put(Contacts.ContactMethods.TYPE, Contacts.ContactMethods.TYPE_WORK);getContentResolver().insert(uri, values);}

4、新增公司和職務

// add company name & titleString company = "Google?";String position= "CEO!!!";if (!AppUtils.isEmpty(company) || !AppUtils.isEmpty(position)) {values.clear();uri = Uri.withAppendedPath(newPersonUri, Contacts.Organizations.CONTENT_DIRECTORY);// company nameif (!AppUtils.isEmpty(company)) {values.put(Contacts.Organizations.COMPANY, companyNameText);}// positionif (!AppUtils.isEmpty(position)) {values.put(Contacts.Organizations.TITLE, positionNameText);}values.put(Contacts.Organizations.TYPE, Contacts.Organizations.TYPE_WORK);getContentResolver().insert(uri, values);}

二、查詢

要實現查詢功能，可能需要有點SQL的基礎。

1、查詢人名

// the contents want to getString projection[] = new String[] { People._ID, People.NAME };// the name to be foundString name = "find me";// start searchCursor cur = getContentResolver().query(People.CONTENT_URI, projection, // select sentencePeople.NAME + " = ?", // where sentencenew String[] { name }, // where valuesPeople.NAME); // order byif (cur.moveToFirst()) {// get the resultsdo {String id = cur.getString(cur.getColumnIndex(People._ID));String name = cur.getString(cur.getColumnIndex(People.NAME));} while (cur.moveToNext());}// close while finishif (cur != null) {cur.close();}

通過修改projection的內容，可以取得不同的內容。

2、查詢電話號碼

如果要獲得電話號碼，就可以改成（id由上面的程式碼獲得）

String phoneProjection[] = new String[] { Contacts.Phones.PERSON_ID, Contacts.Phones.NUMBER };Cursor phoneCursor = getContentResolver().query(Contacts.Phones.CONTENT_URI, phoneProjection, // selectContacts.Phones.PERSON_ID + " = " + id, // where (another style)null, Contacts.Phones.DEFAULT_SORT_ORDER); // orderif (phoneCursor.moveToFirst()) {// get the resultsdo {String phone = phoneCursor.getString(phoneCursor.getColumnIndex(Contacts.Phones.NUMBER));} while (phoneCursor.moveToNext());}// close while finishif (phoneCursor != null) {phoneCursor.close();}

3、查詢email地址

如果要獲得email地址，稍微麻煩點

String emailProjection[] = new String[] { Contacts.Phones.PERSON_ID, Contacts.ContactMethods.KIND, Contacts.ContactMethods.DATA };Cursor emailCursor = getContentResolver().query(Contacts.ContactMethods.CONTENT_URI, emailProjection, // selectContacts.ContactMethods.PERSON_ID + " = " + id, // wherenull, Contacts.ContactMethods.DEFAULT_SORT_ORDER); // orderif (emailCursor.moveToFirst()) {do {int kind = emailCursor.getInt(emailCursor.getColumnIndex(Contacts.ContactMethods.KIND));if (Contacts.KIND_EMAIL == kind) {email = emailCursor.getString(emailCursor.getColumnIndex(Contacts.ContactMethods.DATA));}} while (emailCursor.moveToNext());}// close while finishif (emailCursor != null) {emailCursor.close();}

三、修改
